SAMPSON W. MOON, OF CHICAGO, ILLINOIS.

ELECTRIC VIBRATOR.

Specification of Letters Patent.

Patented May 17, 1910.

Application filed December 24, 1906. Serial No. 849,318.

To all whom it may concern:

Be it known that/I, Sairrsoxjlv. Moon, a citizen of the United States of America, and resident of Chicago, Cook'county, Illinois, have invented a certain new and useful Improvement in Electric Vibrators, of which the. following is a specification.

My invention relates to improvements in electrical vibrators or massage machines.

The object of the invention is to provide a vibrator adapted to be operatedwvithout a motor and for use in connection with the direct, alternating or battery currents.

A further object is to provide a vibrator adapted to produce both'percussion orhammer strokes and lateral strokes, and con structed in such a manner that the strokes of the armature will-be but slightly affected by the hardest pressure of the applicators when running at either higlror low speed.

A further object is to provide a device whereby larger and heavier tools, especially hammers, chisels, punches, surface grinders,

cutters, etc, may be used if desired.

These and such other -ob]ects as may hereinafter appear are attained by my device, an

embodiment of which is illustrated in the accompanying drawings, in which Figure 1 represents a perspective View showing my improved device with a condenser inserted between the apparatus and the plug. Fig. 2 a plan view of my device with the top removed and parts of the instrument broken away. Fig. 3 is a sectional view on line 3-3 of Fig. 2, looking in the direction indicated by the arrows. Fig. 4 is a sectional view on line 44 of Fig. 2, looking in the direction indicated by the arrows. Fig. 5 is a sectional view on line 55 of Fig. 2, looking in the direction indicated by the arrows.

Like numerals of reference indicate'like parts in the several figures of the drawing.

Referring more particularly to the drawings, 1 denotes the casing in which the operating parts of the machine are. contained, the same being here shown, and is preferably of oblate spheroid shape. To the lower side of the same is reniovably connecteda hollow handle 2 through which the end of theflexible conductor. 3 passes to be connected to the operating parts of the device. ()n the op )0- site end of the conductor 3-which is prefer ably in the form of a silk covered wireis arranged a contact plug 4 adapted to be screwed into an ordinary incandescent light with the necessity of providing a separate support therefor, the condenser being constructed and arranged in a small compact form and covered by a casing to present an attractive appearance.

In the casing 1 is secured a suitable supporting frame 6 on whih is mounted an clectro-magnet 7, said magnet' being connected to the inner end of the conductor 3 and energized by-the current passing therethrough. Pivotally mounted 1n a bracket 8 ofthe frame 6 is an armatur'e 9 adapted to be attracted by the electro-magnet- 7. Connected to the armature 9 on one side of the magnet 7 and adjacent to'the pivoted end of. the a rm'ature is a coiled retracting spring 10, the oppositeend of which is cdlniected to a screw 10'which is longitudinally mounted.

turned to vary the tension of the spring 10.

(The'said button has ajpin 10 which ,engages a stop 10 on the casing to limit the adjustment of the spring 10 and hence of the armature.)

Although the device as previously in use would work properly on alternating currents as regards speed and power, there have been no' ways devised to regulate said speed and power, as they were practically the same regardless of the adjustment of contact point'sthat is, they were the same whenjghe contact was first made as when the contact points were almost closed. This is not the case when the direct currentis used,

as in this case the strokes are slow and short when contact is first made, and gradually increased in speed and length as the s ace is lessened between the contact points. 0 secure the various speeds and lengths and also power of strokes of armature on the alternating' machine, I have attached the button above described to the retraction spring, which adjusts'said spring so that the speed, power and size of strokes may be perfectly regulated. By the use of this ad uStment button, the machine may be used for either an alternating current or a direct current without changing the windings of the magnet, rovided the proper resistance is placed .in't e circuit. This is an important adriations in voltage and cycles in the alternating current,that,is, to the extent. of a variation of ten cycles or ten volts either higher or lower than that for which the niachine is originally intended. Arran 'ed on the opposite side of the magnet 7, and bear ing'upon theinner side of the armature adjacent to its free end, is a push spring 12, said springs 10 and 12 serving to evenly balance the armature and to normally hold the same out of engagementwith the magnet. 'Secured to the outer free end of the armature is a. weight 13 which serves as a hammer head 'to impart the vibrations of the armature to the applicators of the ma chine. .The outward push of the Spring 1:? on the armature is constant, but the pull of the spring 10 thereon maybe varied by turning the button, as hereinafter described, and hence the spring 10 may be caused to counteract the spring 12 to any desired extent, and the force of the strokes of the hammer may be regulated accordingly.

Nearthe inner or pivoted end of the-armature s secured the armature spring 14.

which is in electrical engagen'icnt with an arm 15 to which one of the wires of the conductor 3 is connected. The opposite end of the spring libears upon a hollow plug LU formed of suitable non-conducting i'nateria u and arranged in a bracket 17 on the frame 6. In the inner end of the hollow plug 16 is arranged a threaded-metallic sleeve 18 which is in electrical connection with the conducting wire from the magnet. Adapted to be screwed into the sleeve 18 is an adjustable contact screw 19, the inner end of which is adapted to be screwed in engagement with the inner end of the contact spring 14 to complete an electric circuit, thereby causing the magnet to attract and vibrate the arma ture. By adjusting the screw L9 in the sleeve 18, the speed, power and length of the vibrationsof the armature may be regulated. ()n the outer end of thcscrcw 19 is arranged a head 20, and on the screw between said head and the bracket 17 is arranged a coiled spring 20, the tension of which is exerted to hold the screw in its ad justcd position. On the head 20 is arranged-a radially projecting pin or pointer 21'which is adapted to coact with a scale arranged on the outer side of the casing} around the head 20 to indicate the different adjustments.

Arranged in the casing 1 adjacent to one side of the magnet is a. vibrator post 23, on the onterjside of which, adjacent toits upner end, is formed an outwardly projecting socket 2* which projects through an aperture in the casing 1,.and is provided in its outer cndwith interior screw threads and into the threaded outer end of the socket 2% various formsof applicators are adapted tobe screwed. ()nthe inner side of the post directly opposite to the socket 24 is formeda recess in which is secured an inwardly projecting rubber plug or bumper 26, which is adapted to be struck by the weight or hanr mer 13 on the free end of the armature, and through which the vibrations ofthearmature are imparted to the post. The plug or bumper 26 is employed to prevent the armature from striking the-poles of the magnet. The rubber bumper also prevents the hammer or weight 13 from directly striking the post and thus deadening the noise which would be occasioned by such direct stroke.

Formed on the outer edge of the post adjacent to its upper end is an inwardly projecting vibrator arm or plate 27, to the end of which is secured a right-angularly projecting socket 528 which extends through an opening 29 in the side of the casing 1, and

projects at substantially a right angle to the socket 24. The socket 28 is threaded 'lliwardly and is adapted to receive the various forms of applicators 30, to which lateral strokes are imparted by the action of the hammer, direct or percussion strokes beingimparted to the applicator-31 attached to the socket 24. Providing a vibrating post separate and apart, ,or structurallydistinct,

from the armature to receive the strokes or vibrations thereof, instead of connecting the armature directly with the applicators, leaves the armature entirely free, and the pressure of the applicators will not ali'ect the.

speed or opcralion of the armature. whether the same be working ata high or low speed.

15y arranging the machine to produce both a percussion or hammer stroke and a lateral stroke, the capacity and usefulness of the device will be greatly increased, the two kinds of strokes being produced without changes of the operating parts or providing switches and other complicated mechanism both strokes being produced at the same time without interfering with each other.

flu connection with the vibrator, I employ many difi'crcnt forms of applicators to be used on various parts of the body, besides those shown in the drawings. In Fig. 2, in dotted lines, is shown the form ofapplicato'r used for facial massage, the same being constructed of soft rubber and in cup shape. The construction and arrangement of the vibrator as herein shown and described onables the same to be practically operated by 7 high or low voltage, direct currents, and

high or-low voltage, direct battery current chine as herein shown is that the same ma be operated by alternating currents of di ferent voltages and cycles by employing the same in connection with asuitable resistance, and by properly adjusting the spring 10 by means of the screw 10 and button 10. By providing a vibrator .post arranged between the armature and the applicators, there is practically no pressure or resistance on the armature, allowing the same to swing freely, thus requiring but little current to operate the machine and producing but slight wear upon the contact members.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation. Various, changes in the form, proportion and the-minor details of construction may be resorted to withoutdeparting from the principle or sacrificing-any of the advantages of the invention, as defined by the appended claims.

In machines designed for use on direct current only, the button 10-ma'y be dispensed with, and the spring 10 secured rigidly to the frame, as ,all necessary regulation of current and vibration ofthe armature is taken care of-by the button 20.
